FOUNT FOB PERCOLATOBS.

Specification of Letters Patent.

Application filed May 16, 1914. Serial No. 839,086.

To all whom it may concern:

Be it known that we, FRANK KUHN and FRANK E. SI-IAILOR, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Founts for Percolators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to founts for percolators and comprises the novel construction as hereinafter set forth.

In the drawings: Figure 1 is an elevation of the lower portion of the fount casing showing the valve and seat detached; Fig. 2 is an enlarged sectional view showing the valve in operative position; Fig. 3 is an elevation partly in section, of a percolator provided with the fount.

A is the bottom of the liquid-holding receptacle having the hot well B formed therein.

C is a tube having its lower end of a diameter corresponding to the diameter of the well B with a cylindrical portion extending upward therefrom terminating in the tapering portion D, connecting with a straight portion E of smaller diameter.

F is a branch tube connected with the cylindrical portion C and inclining downward therefrom. The lower end of this branch tube is provided with. notches Gr in its periphery and is also threaded to engage a threaded cap member H forming a seat for a disk valve 1. This valve is provided with a central stem J which engages an apertured spider K in the tube F.

When the valve and seat cap are in position, as shown in Fig. 2, the valve disk will normally seat by gravity to close the opening into the inclined tube F. When, however, the pressure within said tube is less than that of the surrounding liquid the valve will open, permitting the liquid to enter and pass around the edge of the disk into the tube F. The disk I is of only slightly smaller diameter than the tube F, but the notches G in the lower end of said tube form a clearance space for the passage of the liquid around the periphery of the (topics of this patent may be obtained for five disk. Also the periphery of thedisk may, if desired, have one or more notches ll there in to provide a greater clearance.

W hat we claim as our invention is 1. In a percolator, the combination with a receptacle provided with a hot well, of a fount, comprising a tube having a cylindrical lower portion of a diameter corresponding to the diameter of the hot well and registerable therewith, said tube having also a tapering portion for connecting said cylindrical portion to an upper portion of smaller diameter, a laterally and downwardly inclined branch connecting with said tube, a disk valve in the lower end of said inclined tube, and a seat for said valve secured to the lower end of said tube.

2. In a percolator, the combination with a receptacle provided with a hot well, of a fount, comprising a tube having a cylindrical lower portion of a diameter corresponding with the diameter of the hot well and registerable therewith, a tapering portion above said cylindrical portion and an upper portion of lesser diameter, an inclined branch tube having a threaded and notched lower end, a threaded cap for engaging said lower end centrally apertured to form an in let port, and a disk for closing said port arranged within the notched portion of said tube.

3. A fount for percolators, comprising a tube having a cylindrical lower portion, a tapering portion above the same and a straight portion of smaller diameter above said tapering portion, a laterally and downwardly inclined branch tube having a threaded and notched lower end, a spider forming a central bearing within said tube, a valve disk provided with a stem engaging the bearing in said spider, and a cap member threaded to engage the threaded end of said tube and apertured to form a port with a surrounding annular seat for said valve disk.

In testimony whereof we aflix our signatures in presence of two witnesses. FRANK KUHN. FRANK E. SHAILOR. Witnesses ROLAND Dnnssnn, STANLEY B. OAKns.
